Trade only? : yes
The first time reaching legend is always the worst, but with time it gets easier and sometimes you reach it without even knowing, just by playing randoms games.
Reached legend about 10x before plus this season, one day before the new expansion, and took me 125 games ( 75 - 50 ). it was stressful because i wanted the rewards, but not nearly as stressful as the first time. I think this new system is easier to get to legend for the 'good' players and harder for the unexperienced ones, but like i said, the first time is always the worst.
on the front page on this website, there is a countdown to the new expansion.
